Attraction is an perplexing force, a complex interplay of psychological, physiological, and social factors that draws people together in romantic and platonic relationships. It’s a subject that fascinates scientists and laypeople alike, prompting countless studies to unravel the secrets of human connection. Let’s jump into this overview of the science of attraction, exploring the factors influencing who we are drawn to and why.

Psychological Factors: The Role of Personality and Values

Personality traits play a significant role in attraction. Research suggests that people often seek partners with compatible or complementary personality traits. A study published in the Journal of Personality and Social Psychology found that qualities such as kindness, humor, and intelligence are universally sought in potential partners (Buss, 1989). These traits indicate a partner’s ability to provide emotional support, share life’s joys, and contribute to a mutually fulfilling relationship.

Shared values and beliefs also form a crucial aspect of psychological attraction. According to Finkel et al. (2007) in their work published in Psychological Science, sharing similar values strengthens interpersonal bonds by fostering a sense of unity and understanding. This alignment can include political beliefs, religious affiliations, and life goals, underscoring the importance of shared experiences and worldviews in forming deep, lasting connections.

Physiological Factors: The Power of Pheromones and Appearance

Though less understood, pheromones are considered to play a role in human attraction. These chemical signals, secreted by the body, are believed to influence sexual and social behaviors. A study in the Proceedings of the Royal Society B suggests that pheromones can affect attraction by signaling genetic compatibility, potentially contributing to mate selection by indicating immunological fitness (Wedekind et al., 1995).

Physical appearance, including facial symmetry, body shape, and other physical characteristics, also significantly impacts attraction. Evolutionary psychologists argue that these features are indicators of health and fertility, making them attractive traits in a potential partner. For instance, facial symmetry is often associated with genetic fitness. At the same time, waist-to-hip ratio in women and shoulder-to-waist ratio in men are seen as indicators of fertility and health (Singh, D., 1993).

The Impact of Social and Environmental Factors

The environment and social context in which individuals meet play a crucial role in attraction. Proximity and frequent encounters can increase the likelihood of attraction, a phenomenon known as the “mere exposure effect” (Zajonc, 1968). This effect suggests that simply being in the same environment and having repeated interactions with someone can foster a sense of familiarity and comfort, increasing their attractiveness.

Social and cultural norms also influence attraction, shaping preferences and expectations regarding potential partners. These norms can dictate what is considered attractive in different cultures, from personality traits to physical appearance, indicating the social construction of attractiveness standards.


The science of attraction is a complex tapestry of factors that intertwine to draw individuals together. Various elements contribute to the magnetic pull of human connection, from the psychological allure of shared values and complementary personalities to the physiological influences of pheromones and physical traits. Moreover, the impact of social and environmental factors highlights the role of context in shaping who we find attractive. Understanding the multifaceted nature of attraction enriches our comprehension of human relationships. It illuminates the diverse ways we seek and find connection with others.
